Hello comunity, im new at arduino and made a few small projects on Raspberry Pi.
I want to make a simple effect on led strip like, when turn on, it lights the first led until last one, one by one, and keep all leds on! Is like a slide in effect.
Any ideas where to learn how to do ir?
Kind Regards
Hello puritan
Run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.
Have a nice day and enjoy coding in C++.
Thanks a lot! I will buy an arduino firstly!
Have a nice day!

ahha lets try with arduino 
Maybe start here.
With addressable LED strips you can do almost anything you can imagine! The hardware is super-easy. The software is complicated but most of the hard-part is handled by a library so your part is not too bad.
I haven't done any IR, but if you search for "Arduino IR" you'll get lots of hits.
As always, work on the input (IR) and output (LED control) separately before trying to put everything together.
If you're new to programming start with minimal code and add a few lines of code at a time, test-compiling and test-running as you go. Nobody writes the whole program at once. ...That's not as simple as starting at the top and working down because the compiler has to see a "whole program" that "makes sense".
And make use of the Serial Monitor to "print out" variables or little messages so you can "see" what the program is doing.
...The LEDs can be very CPU-intensive so and you MIGHT have to pause the LED action to read the IR input.
I haven't used an addressable LED strip (yet) but I've used individual LEDs and drivers to do various "chase" effects including something very similar to what your describing. (Mine is sound-activated and triggered by the loudness or the "beat".)
Thanks a lot mate Ill check it!
While you wait for that, or even you could,postpone spending any money at all and try
this Arduino simulator, wokwi.com
which is very easy to use, free and no possibility of damaging anything.
